n. Power of induction; specifically, the coefficient of self-induction. See induction, 6.n. It is the property of an electric current in a circuit (called the inducing circuit) of producing a magnetic field surrounding the circuit, which when changing induces an electromotive force in a circuit surrounded by this field or a part thereof (called the induced circuit). If the induced and the inducing circuit are the same, the property is called self-inductance, otherwise mutual inductance. Unit inductance is the number of lines of magnetic force produced by unit current in the inducing circuit and interlinked with the conductor of the induced circuit: 10 times this unit is the practical unit of inductance, called a henry.
